Hello there.
An atom that has the same amount of atoms of each element on both sides of the reaction obeys what law
<span>law of conservation of mass</span>
Answer:
<h2>

</h2>
Explanation:

<u>First of all cross multiply</u>
That's

<u>Next divide both sides by </u>
<u> in order to isolate </u>
We have

We have the final answer as

Hope this helps you
You did not provide the statements but a possible answer might be that the current atomic theory is sound and that technology that could challenge it does not exist at this time. There is no way to change it because no research can be done about it.
The rules of IUPAC followed for hydrocarbon are
a) We will first find out the longest chain of carbon in the given organic compound including triple bond
the root name will be "hex" as number of carbon atoms in longest chain is six.
b) The triple bond will be assigned minimum number locant. the locant will be 2 .
The primary suffix will be "yne"
hence
hex-2-yne
c) we will give locant number to methyl group (present as substituent)
it will be "4"
Thus the completer IUPAC name will be
4-methylhex-2-yne or 4-methyl-2-hexyne [as given in the options]
